The comparison lists a hull extension of 23.6 feet to accommodate larger power generators. The revised bow removes the sonar dome and changes the forward arrangement for stability. Fixed-pitch propellers are introduced for improved acoustic performance. Displacement growth is initially described as about 500 tons and later approaching 1,000 tons as changes accumulate. Modified topsides accommodate US warfare systems, so the alteration extends well beyond exchanging individual pieces of equipment.

Constellation's bow, propeller, and generator changes
A 23.6-foot hull extension, removal of the bow sonar dome, and fixed-pitch propellers show how specific requirements altered FREMM.
